A large part of FC Twente's stadium has collapsed, according to SSN so far 2 have been killed and 12 have been injured, would hate to think what they figures would have been if there had been a game on at the time. I think it may have been caused due to the steep design of the stadium.
My sympathy goes out to those involved in this and their families.
